3) This device support frame bottom supports longeron and supporting beam and adopts bolted connection, can adjust the distance between two support frames, is applicable to the canvas reel of various models and uses, and the practicality is strong.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the assembly of the present invention;

the figure is marked with: 1. the device comprises a support frame 11, a support longitudinal beam 12, a support rod 13, an inclined support 2, a lifting seat 21, a fixing frame 22, a roller 3, a shaft sleeve 4, a frame seat of a guide opening frame 5, a canvas reel 6, a rotating shaft 7 and a chuck device.

Detailed Description

The present invention will be further explained with reference to the drawings attached to the specification so as to be better understood by those skilled in the art.

Example 1

As shown in fig. 1-2, a canvas unwinding frame lifting device comprises a support frame 1, a lifting seat 2 and a shaft sleeve 3, and is used for assisting the unwinding frame to unwind the canvas.

Support frame 1 is equipped with two, and two 1 symmetries of support frame are found to be located 5 both sides of canvas reel on leading a frame seat 4, hold in the palm and lift 2 fixed mounting on the 1 top of support frame, and axle sleeve 3 is arranged in and is lifted 2 tops and lift 2 roll connections, and pivot 6 runs through axle sleeve 3 and is connected with chuck device 7 leading a both sides behind rather than the fastening connection. The supporting and lifting action is generated on the canvas winding drum 5 through the lifting device, the pressure of the canvas winding drum 5 on the middle part of the rotating shaft 6 is reduced, and the clamping heads at two ends are prevented from deforming due to the fact that the middle part of the rotating shaft 6 bears overlarge pressure; wherein the setting of lifting seat 2 and shaft sleeve 3 guarantees that pivot 6 normally rotates.

Specifically, support frame 1 is including supporting longeron 11 and

bracing piece

12, 11 top middle parts of bracing piece 12 bottom fixed connection support longeron, bracing piece 13 is connected between 12 upper portions of bracing piece and the 11 tip of support longeron, reinforcing support frame 1 structural strength and stability.

Furthermore, two supporting beams 41 are transversely arranged on the guide frame seat 4 in parallel at a preset interval, a plurality of fixing holes are transversely formed in the top ends of the supporting beams 41 at a preset interval, the supporting longitudinal beams 11 are matched with the fixing holes to form mounting holes, and the supporting longitudinal beams 11 are fixed above the supporting beams 41 through the mounting holes by bolts. When the device is used, on one hand, the distance between the two support frames 1 and the canvas winding drum 5 is ensured to be the same through the measurement of the mounting holes, and the balance is kept; on the other hand, be convenient for adjust the distance between the support frame 1 according to the size of canvas reel 5, the suitability is strong.

The lifting seat 2 comprises a fixing frame 21 and rollers 22, the fixing frame 21 is U-shaped, the two rollers 22 are arranged in the fixing frame 21 side by side at a preset distance and are rotatably connected with the fixing frame 21, the top ends of the rollers 22 extend out of the fixing frame 21, and the shaft sleeve 3 is arranged above the two rollers 22 and is positioned between the two rollers 22 and is in rolling connection with the rollers 22.

The shaft sleeve 3 is cylindrical, a square hole is transversely formed in the center of the shaft sleeve 3 and used for being connected with the rotating shaft 6, the rotating shaft 6 is made of square steel with the outer diameter matched with the square hole, and the rotating shaft 6 penetrates through the shaft sleeve 3 through the square hole.

Because canvas reel 5 is heavier, adopts the log as canvas reel 5's spool to adopt the square steel as pivot 6, match the square steel on canvas reel 5's the spool and set up the through-hole, match the square steel on the axle sleeve 3 and set up the square hole, pivot 6 utilizes the figure to agree with and form the dead fixed knot of lock structure with spool and axle sleeve 3 to be connected the back, avoids pivot 6 and axle sleeve 3 or canvas reel 5 to skid, guarantees that canvas reel 5 steadily rotates.

This device simple structure solves 6 both ends dops of prior art pivot and warp the card and do not advance the chuck, needs frequently to change pivot 6, increases material cost and cost of maintenance's problem, and improves the stationarity when pivot 6 rotates, and tension is balanced when guaranteeing the canvas and unreeling, steadily to the gum dipping line output, improves production efficiency.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the spirit and principles of the present invention, various modifications and improvements of the technical solution of the present invention will be considered by those skilled in the art within the scope of the present invention as defined in the appended claims.
